Quick Answer
Start with the target device, port, link distance, fiber type and document needs. Then use the article content below to narrow the model path before sending an RFQ.
What is SFF Transceiver? SFF (Small Form Factor) is welded small package optical transceiver usually with 2×5 or 2×10 pinout, with the general speed of less than 1250Mbps and using LC interface. Small Form Factor (SFF) Transceiver Multi-source Agreement (MSA) was established by defines the package outline, circuit board layout, and pin function definition.SFF small package optical transceiver adopts advanced precision optics and integrated circuit process, those make it is 25% smaller than SFP cage assemblies, 30% smaller than traditional 1×9 transceivers or 70% smaller than GBIC optics.The SFF package allows designers of Gigabit Ethernet networking equipment to maximize their use of available board space.
